With Humans Out of the Way, Humpbacks Are Flourishing—But So Are Orcas

Researchers are just now beginning to understand what happens when one whale species attacks another

The centerpiece is a cast of the reconstructed remains of Prognathodon kianda, which make up the most complete skeleton of this species found to date.

Astrophysicist Michelle Thaller on Understanding Our Place in the Universe

Autodesk vice president Brian Mathews talks with the NASA science communicator about the search for life on other planets and why it’s important

Princepajaro, a male California sea lion, swims in a pool during treatment for leptospirosis at The Marine Mammal Center in Sausalito, CA. When a leptospirosis outbreak occurs, the Center’s scientists study the disease to learn more about what causes an outbreak and how we can improve treatment for infected animals.

Major Disease Outbreak Strikes California Sea Lions

Leptospirosis afflicts sea lions on a semi-regular cycle, but warming waters and migrating fish could make the marine mammals more susceptible

A silica sphere with a radius of 50 nanometers is trapped levitating in a beam of light.

Optical Tweezers Give Scientists a Tool to Test the Laws of Quantum Mechanics

Quantum superposition is one of the great mysteries of physics—a mass existing in two states at once—and scientists hope to probe the phenomenon

This painting of a cattle-like animal in a Borneo cave has been dated at at least 40,000 years old, making it the oldest known figurative rock art in the world.

World’s Oldest Known Figurative Paintings Discovered in Borneo Cave

Dated to at least 40,000 years old, the depiction of a cattle-like animal has striking similarities to ancient rock art found in other parts of the world

Zelia Nuttall, who began an academic career in archaeology after she divorced her archaeologist husband in 1888, is best known for her work on ancient Mexican manuscripts.

The Archaeologist Who Helped Mexico Find Glory in Its Indigenous Past

Disrupting a stereotype of Mesoamerican savagery, Zelia Nuttall brought the ingenuity of Aztec civilization to the fore

Seagrass plants have a large capacity for absorbing and storing carbon on the seafloor.

Underwater Meadows of Seagrass Could Be the Ideal Carbon Sinks

Many ecosystems absorb and store vast amounts of carbon dioxide, and seagrass is one of the most efficient natural carbon storage environments

Khoikhoi of South Africa dismantling their huts, preparing to move to new pastures—aquatint by Samuel Daniell (1805). Pastoralism has a rich history in Africa, spreading from the Saharan region to East Africa and then across the continent.

Ritual Cemeteries—For Cows and Then Humans—Plot Pastoralist Expansion Across Africa

As early herders spread across northern and then eastern Africa, the communities erected monumental graves which may have served as social gathering points

As the first serious scientist to study the legendary creature, Krantz risked his career and reputation on a subject that many consider a joke. And while the museum remembers him as a man who loved science so much that he donated his body to it, another community remembers Krantz as a pioneer in the study of Sasquatch.

The Scientist Grover Krantz Risked It All…Chasing Bigfoot

The dedicated anthropologist donated his body to science and it’s on display, but his legacy is complicated

Baby bats are born tipping the scales at a third of their adult weight, and since mama bats have to carry them until they can fly, at which point they are nearly full-grown, it’s no wonder they start to get a bit physical.

Mama Bats Literally Nudge Their Babies Out of the Roost

Researchers observed mother bats repeatedly prodding their young to motivate them to fledge

In areas made up of less than 70 percent native plant biomass, Carolina chickadees will not produce enough young to sustain their populations. At 70 percent or higher, the birds can thrive.

Ecologists Have this Simple Request to Homeowners—Plant Native

A new study shows how quickly songbird populations fall off when gardens are planted with exotic trees and shrubs

The flavor of chocolate depends on numerous factors, from the soil the cacao plant was grown in, to the length of time the cocoa beans are fermented.

The Science of Good Chocolate

Meet the sensory scientist who is decoding the terroir of chocolate—and working to safeguard the cacao plant that gives us the sweet dark treat

A North Atlantic right whale rests at the ocean’s surface. With an estimated 100 reproductive females remaining, the species could be unable to reproduce naturally in 20 years.

The Plight of the Right Whale

With dwindling numbers due to snags in lobster traps and collisions with ships, the right whale is looking for a way to make a comeback

Eighty years ago, Seabiscuit trounced Triple Crown winner War Admiral.

Scientists Extract DNA From Seabiscuit’s Hooves To Figure Out How He Was So Fast

Eighty years ago, the horse famously trounced Triple Crown winner War Admiral. Did genetics make him an unlikely success?

Freya, a Springer Spaniel, who has been trained to detect malaria parasites in sock samples taken from children in The Gambia. Freya did not participate in the initial study but was trained afterwards to help sniff out malaria in the future.

Good Dogs Could Help Identify Malaria Carriers

In a small proof-of-concept study, trained dogs neared the accuracy rate recommended by the World Health Organization for detecting the malaria parasite
